EQAs and ISO17043:2010 accreditation

GenQA continually implements new EQAs in response to the advancement of genomic testing.  These new EQAs are initially offered in pilot phase.  The complete list can be found at


EQAs and ISO17043:2010 accreditation

The EQAs provided by GenQA are designed to meet the requirements of the international standard, ISO17043:2010. This approach ensures the provision of high quality EQAs across the range of genomic testing. GenQA and UK NEQAS takes the view that EQA is very much more than just a tick box exercise for laboratories to use in achieving accreditation, and the EQAs we provide reflect this belief.


This guidance applies to non-accredited GenQA EQAs only

Accreditation to ISO17043:2010 is specific for individual EQAs and the samples/methodologies within them. EQAs are generally introduced as follows:

It will, by necessity, take a period of time for an individual EQA to obtain full ISO17043:2010 accreditation as there is an UK Accreditation Service (UKAS) ‘extension to scope’ process that GenQA are required to follow.


Whilst using fully ISO17043:2010 accredited EQAs is the ideal, this is not always possible as new EQAs are implemented and developed on a continual basis.   All GenQA EQAs are treated the same whether they are within the scope of ISO17043:2010 accreditation or not. This means that they are managed within the same Quality Management System as accredited EQAs and are operated by the same highly qualified staff, using established working practices in the same way as accredited EQAs during the implementation phase.  


As with all suppliers of services there is a requirement for the laboratory to risk assess the service that they provide. When risk assessing your EQA supplier you should be looking for more than whether the EQA provider is accredited to ISO17043:2010 [This is the ISO standard for Conformity assessment – General requirements for proficiency testing and all UK NEQAS members are accredited to this standard]. Additional considerations when assessing an EQA service would include:
